TYPE-WRiTING MACHINE.

SPEGIFICATION forming' part of Letters Patent No. 762,290, dated June 14, 1904.

Application filed May 14, 1901.

To all w/tmn may concern:

Be'it known that I, Louis P. DISS, a citizen of the United States, and a resident of Ilion, in the county of Herkimer and State of New 5 York, have invented certain new ancLuseful Improvements in Type WVriting Machines, of

which the following is a specification.

This invention relates to the type-actions of writing-machines. v

The principal objects of the invention are to assemble compactly in a front-strike machine a large number of type -bars mounted upon wide bearings, so that they may vibrate freely and accurately to the printing- 1 5 point, to improve the connections between the type-bars and the keys, and to prevent rebounding of the types upon their return to normal position.

Other objects will hereinafter appear.

My invention consists in certain combina tions of devices, features of construction, and arrangements of parts,- all as will be hereinafter fully set forth, and particularly pointed out in the concluding claims.

5 In the accompanying drawings, Figure 1 is a central sectional elevation taken longitudinally of a front-strike writing-machine constructed in accordance with my invention, the parts being shown in normal position. Fig.

3 2 is a fragmentary sectional view showing a long type-bar in printing position. Fig. 3 is a similar view showing another long typeb'ar in printing position. .Fig. 4 is a similar view showing a short type-bar in printing position.

on the line X X of Fig. 1 and showing a typesegment and some of the short type bars mounted thereon. Fig. 6 is a rear sectional elevation taken at about the line Y Y of Fig.

4 1. Fig. 7 is a diagrammatic front elevation of the system of, connections extending upwardly from the key-levers. Fig. '8 is avertical section of a type basket or rest. Figs. 9 and 10 are front and side sectional details of a universal joint between a connecting-rod and a key-lever. Fig. 11 is a fragmentary front view showing the type-bar shield in position.

tails of means at the basket or rest for preventing rcbounding of the type-bars.

In the several views similar parts are designated by similar numerals of reference, and portions of the machine are omitted or broken away to disclose the invention'more clearly.

The framework consists of a rectangular base 1, corner-posts 2, and a top plate 3. A platen 1 (diagrammatically illustrated) may be mounted to move longitudinally over the latter. Forwardly of the platen is a segmental frame 5, which is secured at its ends to lugs 6, rising from the top plate,- and at its lower central portion by screws7 to the rear end of a bracket 8, which at its forward end is fastened by screws 9 upon a cross-bar 10, which is formed integral with the base. Upon the 5 rear Vertical face of the' segment and along its lower curved edge is secured, by means 0f screws 11, a double set of radial type-bar hangers. The front face of the'segme'nt 5 is counterbored at 12 to receive the heads of 7 the screws 11, which pass rearwardly through perforations 13, formed in the segment, and are tapped into the type-bar hangers. The latter are arranged in two tiers, those in the forward tier being designated as 14 and those in the rear tier as 15, the former lying close against the vertical face of the segment and the latter having thickened body portions 15*, whereby they are offset from the segment, thus occupying a position in rear of the hangers 14. 0 As appears at Fig. 6, all of these hangers are forked at their inner ends to provide wide bearings for the type-bars, the forks of the rear hangers 15 overlapping the forward hangers 14 and being farther from the common 5 printing-point than are the forksof the for: ward hangers, and the type-bar pivots at the sides of the system are longer than the central pivots, the outermost pivots being preferably the longest.

The radially and segmentall y arranged rear- War dly and upwardly striking type-bars that are mounted upon the brackets or hangers 14 and 15 are designated, respectively, as 16 and 17, the former measuring less from pivot 95 to type than the latter and each carrying a plurality of type 18.

The type-hars extend the printing-point, while the long type-bars through radially elongated perforations '19 1 move through a little less than one-quarter of acircle, the paths of the types upon the shorter 7 formed in the segment, said perforations being preferably so wide that the type-bars do not contact with the edges thereof The pivots of the type-bars 16 and 17 may increase more or less gradually in length from the middle. to the sides of the system, the body of a type-bar being farther from the bearings of its pivot the nearer the type-bar is to either side of the system. The type-bars at the sides of the segment preferably have hubs 20 of greater wid th than those at the middle portion thereof, the forks of the side hangers being accordingly widened, since these type-bars vibrate in planes which gradually approach the horizontal, and hence have more or less tendency to sag, and it being of especial ima portance to prevent their lateral vibration, which would destroy the vertical alincment of the types at the printing-point.

The above-described pivots and bearings will properly support the type-bars from side to side of the system, and so preserve the alinement for a long time, notwithstanding the tendency of the side type-bars to sag and the peculiar wear to which their bearings and pivots are subjected. Of course the longer the pivots of v the side bars are the less liable is the alinement to be impaired by Wear atthe ends of the pivots. The effect of this wear may be rendered substantially equivalent to that in the bearings of the central type-bars by providing all of-the type-bars of the system with pivots of proper relative lengths. The two or three outer hangers 14L are secured against a step. or face 5 of the segment whose plane is forward of the face upon which the other hangers are secured, so

that these hangers may clear the platen andv usual paper-feeding devices. The pivots of the rearmost type-bars 17 lie in substantially the same vertical plane as the printing-line upon the platen, so that the types upon these bars movein practicallyhorizontal lines when closely approaching the printing-point, and

hence the alinement is nearly as perfect when manifolding as when writing single copies, the increased diameter of the platen due to the placing of additional sheets thereon not having any appreciable tendency to cause the impressions to fall below or above the normal plane of writing, such as would be the case if said pivots were placed far in front or in rear of the illustrated positions.

Arranged between the platen and. the hub portions of the above-described type-bars is a series of short type-bars 21, which are pivoted upon hangers 22, secured by screws 23 to the rear vertical face of the segment 5 and near the upper curved edge thereof. The type- .bars 21 lie nearly in contact with the front vertical face of the segment and diverge ra- They swing through nearly half a circle from normal position to center.

bars being, however, of so bstantially the same length as those upon the longer bars and the pivots of the shorter bars being in nearly the same vertical plane as the pivots of the longer bars 17. The purpose of swing'ng the short type-bars 21 to a point below the usual hori- 1 types upon the short bars, as will be understood by reference to Figs. 2 and When all the bars are in normal position-athat is, at rest-the short bars extend in directions at right angles to or crosswise of the long bars,

and when the latter are in printing positionthey'extend longitudinally of-the short bars.

Preferably I place fifteen short bars in the 1 upper curved row ofhangers 22 and twentyseven long bars in the lower double set of hangers. According to. this arrangement the type-barsare divided into two sets, the bars" in one set extending forwardly from their pivots and the bars in the other set fanning or extending from their pivots radially of the printing-center and being arranged between the pivots of the first set and the printing- Ample clearance for the types is thus secured,and liabilityof collision is avoided. it should be understood, however, that from certain aspects of my present invention and for certain purposes thereof it is immaterial whether or not the upper set of type-bars are employed. The lower set of bars maybe employed alone inthe machine and the number of types on each bar varied at will. The upper side portions of the segment to which the hangers 22 are-fastened are stepped forwardly at 22, 22", and 22, so that the hangers 22 at these points may clear the platen and the usual carriage mechanism.

The" type-bars are operated by a series of levers 24 of the second order, having keys 25 and extending rearwardly beneath the typebars, said levers being fulcrumed upon a transverse bar 26 and provided with returningsprings 27. Each lever is provided with a strap 28, to which is pivotally connected at ITO 29 the lower end of an upwardly-extending I the long type-bars are, arranged forwardly of ,for the long type-bars is connected by a radially-directed link33 to a short arm 34, formed upon its type-bar, said links extending longitudinally ofthe hangers. The bell-cranks or angle-levers are of various shapes and sizes, according to their positions upon the segment, and each is provided with an outwardly-extending arm for attachment to the connectingrod 30. ciated with the long type-bars lie in horizontal planes and are hence parallel. The axes of the three central bell-cranks 31 are parallel with their type-bar pivots, which in these instances swingin planes nearly parallel with the planes in which their key-levers 24 work. Their bell cranks are disposed at various heights over the rear vertical face of the segment. Each of the bell-cranks 32 in the upper tier is connected byia ulink 35 to a sub lever 360i the first order, whichis pivoted be tween the folks of the hanger 22 just below or outwardly-from the type-bar pivot and is connected by a link 37 to the type-bar. One

arm of the lever 36 extends rearwardly and the other forwardly from its pivot, and the general direction of said lever is obliquely downward and forward. The link 37 extends in a radial direction parallel with the typebar 21 and is arranged forwardly of the hanger 22. The hanger 22 at the center of the systern is unprovided with a bell-crank, its lever 36 being directly connected by a rod 30 to a-keylever strap 28', the type-bar in this instance vibrating in substantially the same vertical plane as its key-lever. The pivot of each bell-crank is designated as 38. its point of attachment to the connecting-rod 30 is designated as 39 and its point of attachment to the type-barlink as 40. The point of attachment of the latter to the type-bar is 1-1. Referring particularly to Figs. 3 and 4, it will be seen that the length of the forward arm of the sublever 36 is greater than the distance between the pivot 42 of said lever and the pivot 43 of the typebar 21, whereby the lever 36 in vibrating through an arc of only about ninety degrees is enabled to swing the type-bar through nearly half a circle, the lever 36 having full control of the type-bar throughout thestroke. The pivot 44, by which the link 37 is attached to the type-bar, lies normally at a point below the type-bar pivot s3 and swings to a point above said pivot, when the link The axes of all the bell-cranksasso-' 37'OCCU1HUS a position at about right angles to the lever 36-. Each of the long type-bars rests normally upon a t'elt or leather tip 45, provided upon a radially-arrangcr.l plunger 46, which is arranged in a hole or seat 47, bored radially in a curved bar or segment 48, the segment being supported by ears 49 and screws 50 upon lugs 51, formed upon the front edge of the top plate 3. The diameter of the upper portion of each hole i7 is.reduced at 4:7 to fit a reduced portion or neck 46 ot' the plunger, thus forming a shoulder or stop 47" for limiting the upward movement of the plunger. The plungers are retained in the holes by a curved band 52, which is held in a groove 52 upon the bottom curved edge of the segment 48 by screws 53, said band terminating just below the cars 49 and a leather strip 52 '-being placed between the band 52 and the bottom of the grooveQ- The holes for the plungers at the sides of the basket do not extend through the segment as, but are counter-bored and tapped at 47 to receive screws 54, which are centrally perforated to fit the reduced portions or necks 46 of the plungers. Beneath each plui'iger is placed a coiled conmression-spring 46", one

end of which bears against the leather strip 52" and the-other end of which extends into a shallow hole bored in the lower end of the plunger, the spring having the least possible strength that will hold the plunger in its elevated position, or against the stop 47". When the returning type-bar strikes the plunger, the velocity of the former is instantly reduced and the plunger is driven dmmwardly,both the type-bar and the plunger hence moving min the same direction. As the plunger is lighter than the type-bar, its speed is substantially equal to the original speed of the type-bar, and hence the plunger instantly leaves the typebar, which, as above explained, is now moving at reduced speed. The plunger strikes the stop 52, from. which it rebounds, assisted by the spring 46", and again strikes the type-bar. Thus the velocity of the type-bar is again reduced, the plunger again descends and again rebounds and strikes the type-bar, and in this manner the rebounding ot' the plunger is continued until the energy of the type-bar is exhausted, so that the latter is prevented from rebounding and colliding with other typebar. In other words, the energy imparted to the plunger is at all times less than the opposing energy remaining in the t 'pe-l. ar; but the velocity of the plunger is at all times greater than the velocity of the type-bar, so that the plunger is caused to vibrate between the stop 52" and the type-bar until no space remains in which it can vibrate, when both the type-bar and plunger will come to a state of rest. the bottom end of theplunger resting against the strip 52", from which position it islifted or projected by thespring HWagainst the stop 47" as soon as the typo-bur is started ISO toward the platen. The short type-bars 21 rest upon similar non-resonant tips or plugs 45, :Fig. 5,'provided upon plunger-s or blocks 55, which fit loosely in perforations through which pass the screws 23, that seen re the hangers 22 to the rear face of the segment 5, each of said screws being provided with a collar 57-, which fits in a notch 58, cut in the block 55, so as to prevent displacement of the letter from its perforation 56.

I do not claim to be the first inventor of a rest for the free end of a type-bar comprising a spring-supported cushion, northe combination, with a series of type-bars, of a series of vibratory devices against which the typcbars strike upon returning'to normal position and which are set in vibration by the typebars and absorb energy therefrom; but what I do claim as of my invention with respect to the means for preventing the type-bars from rebounding will be found set forth in some of the appended claims.

Beneath thekey-levers 24 extends a transverse universal bar 59, which is-hung by hooks upon the usual dog-rocker frame 61. The latter is provided with a returning-spring 62 and carries both a feeding-dog 63 and a detent dog 64, said dogs being adapted to cooperate with an escapemcnt-wheel 65, which is con nected to a pinion 66, meshing with a rack 67, supported, usual, upon the platen-carriage. (Not shown.)

I arrange over the type-bars an apron or shield comprising a horizontal supporting portion 68, which extends across the type-bar system and iscut away-at 69 to afford a passage forthe types, and also comprisingadownwardly-extending portion '70, whose lower edge is curved concentrically with and overlaps the type-basket or forward segment 48.- lheportion 68 of theshield is provided with 1 legs? 1, having perforhted feet 72, which rest ju'iorr bosses 73 upon the upper side of the op plate 3 and fit over studs 74, projecting v upwardly from said bosses. are tapped upon the studs 7a, so as to secure the feet 72, and hence the entire shield, in po sition.

Referring to Figs. 9 and 10, it will be seen that-the pivots or trunnions 29 are formed upon the ends or a short cylindrical socketpiece 76, which fits between the upwardlyextending cars 28 of the strap 28. The lower end of the connecting-rod 30 passes down through. a central vertical perforation or socket 77, formed in said socket-piece, and tapped into a cross-pivot 78, which extends.

horizontally therethrough at right angles to the axidthcreof. The rod 30 is thus enabled to vibrate upon the trunnions 29 in a plane parallel vwith the key-lever and also upon the pivot 78- in a plane at right angles to the keylever, said opening or socket 77 flaring sufliciently to enable a crosswise v1- brntion ofthe connecting-rod. llt will be Wing-nuts print.

seen that these parts form a universal joint, thereby avoiding the liability of cramping due to the diverse pivotal movements of the key-levers and bell -cranks.

In operation when a key 25 associated with one of the lower type-bars is depressed the lever 24 is vibrated downwardly upon the fulcrum 26 and through the rod 30 pulls down the bell-crank 31 or 31, as the case may be, causing said bell-crank to vibrate and through the link 33 swing the-type-har .up to At the same time the universal bar 59 iscarried down and the dog-rocker-framc is 'ibrated. When the keyis released, the parts are returned to normal position by the springs 27 and 62, and the platen-carriage is advanced a step in the usual manner. /V one of the keys 25 associated with the upper type-bars is depressed, the rod 30 vil'irates the bell-crank and the latter, through the link 35, swings, the lever 36, which by means of the driving-link 37 swings the -type-bar up to print, and upon relief of thekey from pressure the parts return to normal position, the carriage of course feeding a letter-space.

it will be observed that the short type-bars 21, which are pivoted to strike rearwardly against the platen, fan downwardly and out wardly from their pivots and lie radially of the printing-point, each of said type-bars being connected by a short thrustdink 37 to an arm 36, pivoted at 42 and connected to a key, so as to be operated thereby; that said links 87 are adapted to both travel and turn' bodily about the type-bar axes during theswinging of the type-bars-to the printing-point, as'will besee-n by comparison of Figs. Band 4; that said links are curved so as to clear the pivotal ends of the typebar supports 22 when the type-bars are at the printing-point; that-the direction of each of said short links at the printing moment is crosswise to its normal direction; that during the printing strokes the free ends of the key-operated arms'36 move constantly nearer to the -typehar piv- -ots; thatthe type-bars 21 swing through considerably more than ninety degrees from normal position to the printing-point; that the links 37 are pivoted to said type-bars below the pivots of the latter; that the distance between each type-bar pivot and the-point of attachment of its link to the pivoted arm 36 is normally greater than the length of the link, but at the printing moment less than the length of the link, the purpose of providing this relative arrangement and movement of the arm36 being to enable the same to swing the type-bar through considerably more than a quarter of a circle, and also that the arms 36, which vibrate through less than ninety degrees, are directly connected to the type-bars by the short links in such a manner as to enable said arms to drive the type bars through about one hundred and eighty degrees more or less, a
